Yield of mandarin fish per mu

The yield of mandarin fish ranges from 4000 to 8000 jin per mu. Different culture environments and techniques are the important reasons for the difference in yield. In addition, the growth rate of mandarin fish is fast, raised for 4-5 months, can grow to about 300 grams of commodity specifications.

Points for attention in mandarin fish culture:

1. Breeding ground

The bottom of the pond is required to be hard, less silt, close to the water source, convenient drainage and irrigation, no domestic and industrial sewage inflow, the area of fish ponds without bait should not be too large, generally 1-3 mu. Under the condition of bait fish pond, the area is 2-5 mu. Before stocking, ponds should be regularly cleaned and disinfected to kill all kinds of disease organisms and pathogens. After water injection, 1-2 days before the mandarin fry were put into the pond, the mixture of 0.7PPM copper sulfate and ferrous sulfate (5:2) was sprinkled in the whole pond to kill the parasites in the water so as to improve the survival rate of mandarin fish (especially summer flowers).

two。 Mandarin fish feed

The sources of feed fish for feeding mandarin fish are artificial feeding and wild fish collection. the requirements for bait fish are as follows: live, palatable size, no hard spines, timely supply, and try to meet the above requirements in order to achieve good benefits. All small fish, shrimp and Loach without hard spines can be used as bait fish for mandarin fish, but from the aspects of source, economy and preference for food, dace, crucian carp, silver carp and mackerel should be selected.

3. Culture water quality

The pond water quality of sweet-scented osmanthus fish is medium fat, the transparency is about 30cm, and the water quality is refreshing and oil-green. In addition, each time the water exchange should not be too much, generally the water level around 30cm is suitable, the water exchange is too large, the sharp change of pond water environment will cause sweet-scented osmanthus fish to produce stress response and cause disease.

In fact, mandarin fish is often said to be sweet-scented osmanthus fish, also known as seasonal flower fish, crucian carp and so on, is a famous specialty fish in Guangxi, China. Friends who go to travel or work in Guangxi must not miss this fat mandarin fish.
